The invention relates to an automatic classifying and identifying method of a road line point cloud based on three-dimensional laser reflection strength. The automatic classifying and identifying method comprises the following operation steps of acquiring point cloud data by utilizing a laser scanner, ...
In differentiating the typical group from ASD children with and without ADHD using gaze-adjustment and significant spatial features (Table 3), the AdaBoost algorithm achieved a 17.5% lower accuracy rate than when classifying typical and ASD populations. Also, combining the gaze-adjustment features wit...
parallel lines, naming segments, rays, and lines, identifying parallel and perpendicular lines, acute, obtuse, and right triangles, classifying scalene, isosceles, and equilateral triangles by side lengths or angles, finding an angle measure of a triangle given two angles, naming polygons and so...
Fig. 2. Flowchart for classifying the four groups including HC, SZ, SAD and BPP using dynamic connectivity measures. We used the 10-fold cross validation with 100 runs to maximize the reliability. Within each run, feature selection was first performed only based on the training data (i.e. ...
Chauvinet al.[2]apply a background subtraction using a clear sky image to tackle the issue of misclassifying pixels in the circumsolar area. It sets a threshold to the difference ofNRBRbetween the original image and the clear sky image. The clear sky image is generated from the original im...
Respective picture elements on an approximate border line 15 of the object 1 at the time of the classifying work are, for example, the logic value '1', and other picture element is the logic value '0'. The approximate border line 15 can be shown as numeric data 16 of an (n) number...
Alternatively, the output light may be a combination of wavelengths and output angles. The above techniques are discussed in more detail herein and/or in the aforementioned patent application. The detector 29 has the necessary optics, electronics, software and/or firmware to perform the functions ...
(BaB2O4), has a large birefringence and UV transparency to 200 nm, allowing it to serve multiple roles as a doubler, tripler, or quadrupler of the fundamental Ti:sapphire wavelengths. For proper multiplication, as the Ti:sapphire wavelength is tuned, the angles for the BBO crystals must ...
This example also highlights three important facts. The first fact is that approaches such as latent semantic indexing [7], which are extremely effective at classifying large collections of documents on a broad topic, are unlikely to identify small focused collections that are typical in a storylin...
comprises images from several points of view for each workpiece of the plural workpieces, providing a second data set of images comprising images for each workpiece from several pregiven alignment angles and providing a neural network having a feature extraction part (13) and a classifying part (...
